ATTORNEY,
UNITED JOHN B. MORAE, OF MOUNT HOLLY, ARKANSAS.
SAW-MILL DOG.
SPECIFICATION forming part of Letters Patent No. 388,989, dated September 4,1888.
Application filed May 3, 1888.
To all whom it hwy concern:
Be it known that I, JOHN B. MGRAE, of Mount Holly, in the county of Union and State of Arkansas, have invented a new and Improved Saw-Mill Dog, of which the following is a full, clear, and exact description.
My invention relates to an improvement in saw-mill dogs, and has for its object to provide asimple,eeonomical,and effective device which may be readily and expeditiously manipulated, and which will not easily become disordered.
The invention consists in the construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claim.
Reference is to he had to the accompanying drawings, forming apart of this specification, in which similar figures of reference indicate corresponding parts in all the views.
Figure 1 is a side elevation of the device. Fig. 2is a front elevation of the same. Fig. 3 is a plan view. Fig. 4 is a central vertical section, and Fig. 5 is a side elevation of a modified form of the device.
In the forward end of the base the usual knee, 11, is upwardly projected, and to the opposite end of said base a segmental rack, 12, is attached or cast integral therewith. To one face of the knee 11 aligning blocks 13 and :14 are pivoted, the contiguous surfaces of which blocks are cylindrical, and provided with a series of teeth, 15, the teeth of the several blocks being adapted to mesh, as best shown in Fig. 1. The opposite ends of the several blocks 13 and 14 are recessed, as shown at 16 in Fig. 4C, in which recesses outwardlyextending curved dogs 17 are secured, preferably by means of a key, 18, the said dogs being provided with a head, 19, which cooperates with the key in holding the tooth in place. Ordinarily the blocks are held upon their pivots through the Serial No. 272,714. (No model.)
medium of a plate, 20, which plate is apertured to receive the several posts upon which the blocks are pivoted, the key 21 being projected vertieall y downward through the pivots outside of the said plate, as clearly illustrated in Fig. 2. Below the toothed surface of the lower block, 14, a lever-arm, 22, is attached or east integral therewith, which lever is adapted to slide upon the side of the rack 12, being provided at its extremity with a springlatch, 23, adapted for engagement with the recesses of the said rack.
If in practice it be found desirable,the teeth upon the blocks 13 and 1t may be dispensed with and aprojection or lug, 24, be substituted, which projections are located upon opposite sides and connected by a link, 25, as shown in Fig. 5.
In the manipulation of the device, when the lever-arm 22 is carried upward, the outer ends of the several blocks are carried in the direction of the rack, and the dogs following the movement of said blocks are opened and release the log. To clamp the log, the leverarm 22 is carried downward a suiiicient distance and secured upon the rack by means of the spring-latch 23.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
In a saw-mill dogging apparatus, the combination, with the blocks 1.3 and 14, having extensions provided with recesses and pivoted and connected at their contiguous sides, as specified, of the detachable dogs 17 and keys for locking them in said recesses, as shown and described.
